I like the Senior Railpass idea. Pay for a pass that gives you discounts.
At last! Someone speaking up for the railways!
I have a "Senior Citizens"rail pass and use it mostly to go to London.
There are a plethora of Rail Passes, all of which give you discounts of one sort or another, particularly on non commuter time trains. They are essentially load management tools as the cost of running a train is almost the same, full or empty. So it pays for the operating companies to encourage the uses of off peak tickets.
I don't consider the rail cards to be comparable with the buss pass and other government funded payouts for old people.
